Abstract
Electron-density profiles up to have been measured for plasmas produced on glass microballoon targets irradiated by nanosecond, C-laser pulses in the intensity range 2× to 6× W . Critical-density scale lengths of ∼ 3 μm and plateau structures, including overdense bumps, have been observed. Upper-shelf densities were greater than those attributable to radiation pressure alone, possibly indicating contributions from the superthermal plasma blowoff and self-generated magnetic fields.
